A source and a sink with strengths of equal magnitude, q = 3π m2/s, are placed on the x axis at x = −a and a, respectively. A uniform flow, with speed U = 20 m/s, in the positive x direction, is added to obtain the flow past a Rankine body. Obtain the stream function, velocity potential, and velocity field for the combined flow. Find the value of Ψ = constant on the stagnation streamline. Locate the stagnation points if a = 0.3m.
